Abstract: A plastic formwork is disclosed, and comprises a slurry-receiving structure, wherein the slurry-receiving structure defines an aperture and a formwork-defined internal space, wherein a slurry is receivable within the formwork-defined internal space. The formwork further comprises a formwork-defined first connection system counterpart and a formwork-defined second connection system counterpart, each of which includes a sealed interface-effecting portion that is supported by a substrate portion. The material of the sealed interface-effecting portion is softer than the material of the substrate portion. The formwork is connectible to another formwork via interlocking engagement with effect that an obtained aperture and an obtained internal space are obtained, wherein a slurry is receivable within the obtained internal space.

Abstract: A beam-column clamp apparatus is disclosed. The apparatus includes first and second clamping members with hook like distal portions to clamp the beam. The first and second clamping members are in opposed relation to each other. A leg projects downwardly from each clamping member. The legs are received within the first end of the column and co-operate with each other to secure the first and second clamping members to the column.
